introduction

In the naming of P235GH seamless carbon steel pipe, "P" represents the pressure vessel, the number "235" represents the minimum yield strength of 235MPa, and "GH" represents the hot processing conditions. This material is increasingly valued in the industry for its excellent mechanical properties and high temperature resistance.
In the chemical production process, P235GH carbon steel pipes are often used to manufacture storage tanks, reactors, heat exchangers, pipelines and other equipment. These devices need to withstand extremely high pressures and temperatures when operating, so they require materials with very excellent properties.
For P235GH steel pipe materials, the conventional heat treatment method is normalizing and quenching, and annealing can also be performed. Normalizing and quenching can make P235GH seamless steel pipe obtain higher strength and toughness, and improve its tensile and impact resistance. Annealing treatment can reduce the stress of the material, improve the processability and plasticity of the material, and improve the toughness and corrosion resistance of the material.
In short, P235GH carbon tube can be heat treated to improve its performance. The specific heat treatment method to be used needs to be determined based on the specific use requirements and the condition of the material.
